Nanozymes, characterized by their combination of the favorable catalytic activity of biological enzymes with the structural properties of nanomaterials, have emerged as effective substitutes for natural enzymes. They exhibit high stability, adjustable activity, and robust environmental tolerance, which makes them as ideal candidates for various applications. The exceptional catalytic properties have facilitated their widespread adoption in colorimetric sensing analysis, particularly when integrated with paper substrates. Paper, renowned for its low cost, high porosity, and biodegradability, serves as an excellent platform for developing simple and effective point-of-care testing (POCT) tools. In this paper, we first delve into the construction and operational principles of paper-based colorimetric sensors. These sensors leverage the unique characteristics of paper to create microfluidic channels and reaction zones, enabling the controlled flow and mixing of analytes with detection reagents. The colorimetric response, resulting from the catalytic reaction between the analyte and the nanozyme-based reagent, serves as the basis for qualitative and quantitative analysis. Subsequently, a comprehensive overview of the types of nanozymes and their catalytic reaction mechanisms is provided. Nanozymes encompass a wide range of materials, including metal oxides, metal sulfides, carbon-based nanomaterials, metal-organic frameworks, and single-atom nanozymes, etc., each exhibiting distinct catalytic properties tailored for specific sensing applications. The catalytic reactions involve the oxidation or reduction of analytes, leading to a color change that can be visually detected or analyzed using a smartphone or spectrophotometer. Furthermore, the significant applications of paper-based colorimetric sensors based on nanozymes for POCT are reviewed, focusing on key areas such as food safety analysis, environmental quality monitoring, and biomedical diagnosis. Despite lots of advantages, paper-based colorimetric sensors based on nanozymes face several challenges in the field of POCT. These include limitations in detection sensitivity, biosecurity, and integration with advanced technologies for real-time data analysis. In conclusion, the field of paper-based colorimetric sensors based on nanozymes for POCT is rapidly evolving. With ongoing research and technological advancements, it is anticipated that these sensors will overcome current challenges and offer even more accurate, rapid, and user-friendly solutions for POCT applications in various fields. Their potential to revolutionize healthcare, food safety, and environmental monitoring is immense, making them a promising area of research for the future.
